Deltana SS45 4-1/2" x 4-1/2" Square Corner Hinge, Stainless Steel (Pair)

That is the reason the SS45 exists. Deltana's stainless steel hinges are made for waterside properties and outdoor use, with better corrosion resistance than plated steel hinges. On an oceanfront or poolside opening, a plated steel hinge will rust and streak the door; solid stainless holds up. The finish offered is Brushed Stainless.

No. The SS45 is not an NRP hinge, so the pin can be driven out from the hinge side. On an outswing door where the barrels are exposed outside, that is a security concern and you should specify an NRP hinge, such as the Hager BB1168 NRP full mortise ball bearing hinge. For inswing doors the pin is protected and the SS45 is not an issue.

The SS45 is a standard full mortise hinge with a plain bearing and no closing spring. The Stanley 2060R is a full mortise spring hinge with square corners at 4-1/2 inch by 4-1/2 inch on a ferrous steel base, rated heavy duty - it matches the SS45's leaf size and corner while adding self closing action. Note the SS45 is stainless steel and the Stanley spring hinge is a ferrous steel base, which matters on a coastal or exterior opening.

The SS45 is a stainless steel hinge, which is why it suits waterside and outdoor openings where corrosion resistance matters. For interior residential doors where that is not a concern, the Delaney RH35xx is a 3-1/2 inch by 3-1/2 inch bulk steel residential interior hinge with a 5/8 inch radius corner, sold in pairs, and the Emtek 91013 is a 3-1/2 inch by 3-1/2 inch residential plain bearing hinge with square corners in plated steel, also sold in pairs. Match corner style to the existing door mortise: the Emtek is square cornered like the SS45, the Delaney is radius.

The SS45 is designated for residential use and carries a plain bearing. For a commercial door, the Ives 3CB1 is a steel 3-knuckle concealed bearing full mortise hinge rated medium duty, and the Ives 3CB1HW is a heavy weight concealed bearing full mortise hinge with 3 knuckles rated heavy duty. Both mount full mortise the same way the SS45 does, so the leaf preparation concept is the same, but confirm leaf size and corner against the existing frame prep.

No. The SS45 is a plain bearing full mortise hinge with no electrical provision. For electrified openings, the Command Access ETH-CB70 is an energy transfer hinge with a 3-knuckle standard weight steel base rated medium duty, the ETH-BB68 is a 5-knuckle heavy duty energy transfer hinge, and the Command Access ETM-CB70 adds door position sensing on a 3-knuckle steel base. Stanley's CECB1900R54L is a three knuckle concealed bearing concealed conductor hinge, steel full mortise, standard weight, 4-1/2 inch by 4-1/2 inch square corner, left-handed, 4-wire - that one matches the SS45's size and corner directly.

Two traps. Radius corner hinges such as the Orca 4014 Series 4 inch by 4 inch 1/4 inch radius corner plain bearing hinge or the Delaney RH45xx 4 inch exterior residential hinge with a 5/8 inch radius will not sit correctly in a square corner mortise cut for the SS45, which has square corners. And half mortise or full surface hinges such as the Hager 1129 half mortise plain bearing hinge or the Hager 990 full surface prison hinge use entirely different door and frame preparation than the SS45's full mortise mounting. Size matters too - the SS45 is 4-1/2 inch by 4-1/2 inch, not 4 inch.

Leaf thickness is .134 inch. That is a standard weight leaf, so it sits in a conventional routed pocket without shimming. If your existing hinge measures noticeably thicker, the door will bind on close when you swap.

No. It is a standard full mortise butt hinge with two identical leaves and a removable pin, so the same hinge works on a left hand or right hand door. You set the swing by which side of the opening you mount it on.

Size and material. The SS45 is 4-1/2 by 4-1/2 inches in solid stainless steel, square corner, plain bearing. The Emtek 91013 is a 3-1/2 by 3-1/2 inch square corner plain bearing pair in plated steel. Use the 3-1/2 inch Emtek on lighter interior doors; use the stainless SS45 where the door is heavier or the opening sees weather.

The SS45 is sold by the pair, so a three hinge door takes two units with one hinge left over or an extra pair across two doors. If you would rather buy the set, the Ives 1010RP is a steel plain bearing residential hinge with square corners sold as a set of 3, and the Schlage Residential S3P1010 is a 3.5 inch by 3.5 inch square corner plain bearing mortise hinge in a pack of 3. Both are smaller leaves than the SS45's 4-1/2 inch, so check the existing mortise before switching.

If the openings are prepped for a 4 inch leaf rather than the SS45's 4-1/2 inch, the Orca 4040 Series is a 4 inch by 4 inch square corner plain bearing commercial hinge rated medium duty, which keeps the same square corner and plain bearing arrangement as the SS45. The Delaney CH401X is a 4 inch by 4 inch commercial ball bearing hinge with square corners if you want a bearing knuckle at that size. Both are steel rather than the SS45's stainless, so keep the stainless on any exterior or coastal-facing door.

The SS45 is a 4-1/2 inch by 4-1/2 inch square corner hinge in stainless steel. For the same leaf size with a different barrel treatment, the McKinney SQ3331 is a square barrel 2-knuckle decorative hinge at 4-1/2 inch by 4-1/2 inch, rated standard duty. For a conventional five knuckle commercial profile at that size, the Stanley FBB191 is a 5-knuckle full mortise standard weight hinge at 4.5 inch by 4.5 inch, rated heavy duty. The SQ3331's two knuckle square barrel reads as a design element; the FBB191 reads as standard architectural hardware.

No. The SS45 is a residential duty plain bearing hinge. Detention openings use purpose built hardware such as the BEST BB855 heavy duty steel double weight concealed ball bearing prison hinge from the Detention Hardware series, or the Stanley BB855 double weight prison hinge at 5 inch by 6 inch furnished with no holes and not swaged. The Hager 990 full surface prison hinge at 3 inch by 4 inch with a welded tip is another heavy duty option for that use.
